摘要：
This paper describes about design and analysis of miniaturized bandpass filter with broad stopband for Global Positioning System (GPS) space application. A bandpass filter with five transmission zeros has been realized through the investigation of a unique symmetrically loaded shunt coupled line with pair stepped impedance stubs. Using even odd mode analysis, the transmission zeros frequencies of the filter response have been verified theoretically. The proposed filter compact size and wide 3dB fractional bandwidth of 57.8% covering the frequency 0.75 to 1.36 GHz. Designed bandpass filter may be useful for GSM 900 MHz, GPS L2 and L5 band application.
